Description

Technical Field

[0001] The utility model relates to the technical field of AGV trolleys, in particular to an AGV trolley with active shock absorption. Background Art

[0002] AGV, also known as automatic guided vehicle, refers to a transport vehicle equipped with electromagnetic or optical automatic navigation devices, capable of traveling along a fixed navigation path, with safety protection and various transfer functions. With the rapid development of the logistics and warehousing industries, AGVs have been widely used in the logistics and manufacturing industries. AGVs automatically transport goods or materials from the starting point to the end point, greatly improving logistics efficiency and operating efficiency. The main advantages of AGVs include: high degree of automation, good flexibility, high safety, unmanned operation, etc. AGVs can be customized according to actual needs to achieve various functions, such as handling, sorting, assembly, etc.

[0003] At present, when AGV is working, it generally obtains environmental road information through external devices such as magnetic strips, lasers, and cameras. However, when the camera of the AGV is in use, some dust will inevitably adhere to the outer wall, which may affect the normal operation of the AGV and cause the AGV to be unable to accurately identify the path or obstacles, thereby affecting its driving. Therefore, an AGV with active shock absorption is proposed. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides an AGV trolley with active shock absorption, which has the advantages of improving the stability of the AGV trolley operation and solving the problem that the AGV trolley cannot accurately identify paths or obstacles, thereby affecting its driving.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an active shock-absorbing AGV trolley, comprising an AVG trolley body, two path cameras and a shock-absorbing assembly, wherein the outer wall of the AVG trolley body is provided with a cleaning mechanism;

[0006] The cleaning mechanism includes two linear modules fixedly installed on the top outer wall of the AVG trolley body, the output shaft of the linear module is fixedly installed with a fixing rod, the bottom outer wall of the fixing rod is fixedly installed with a connecting rod, the bottom outer wall of the connecting rod is fixedly installed with a mounting seat, the front and rear inner walls of the mounting seat are fixedly installed with damping blocks, a card plate is clamped between two adjacent damping blocks, and cleaning cotton is bonded to the side of the card plate close to the path camera.

[0007] Furthermore, the shock absorbing assembly includes two mounting frames fixedly installed inside the AVG trolley body, two shock absorbing springs are fixedly installed on the top outer wall of the mounting frame, four damping plates are fixedly installed on the top outer wall of the mounting frame, and the top outer wall of the shock absorbing spring is fixedly connected to a connecting plate.

[0008] Furthermore, the shock absorbing spring is located between two adjacent damping plates, and the damping plate is arc-shaped and fits on the outer peripheral wall of the shock absorbing spring.

[0009] Furthermore, a mounting groove is provided on one side of the mounting seat close to the AVG trolley body, and the damping block is installed inside the mounting groove.

[0010] Furthermore, the clamping plate is clamped inside the mounting groove and is located between the two damping blocks, and the distance between the top and bottom outer walls of the clamping plate is the same as the distance between the top and bottom inner walls of the mounting seat.

[0011] Furthermore, the distance between the outer walls of the two cleaning cottons on opposite sides is the same as the distance between the two opposite sides of the path cameras, and the cleaning cotton and the path cameras are located in the same vertical plane.

[0012] Furthermore, the lowest height to which the cleaning cotton can move downward is lower than the lowest height of the path camera.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] The active shock-absorbing AGV trolley adjusts the height of the cleaning cotton through the action of the linear module, the fixed rod and the connecting rod. The cleaning cotton is fixed inside the mounting seat through the action of the mounting seat, the damping block and the clamping plate, and slides up and down to regularly clean the outer wall of the path camera, which greatly reduces the adhesion of dust and improves the stability of the AGV trolley operation.

The card plate 12 is clamped inside the mounting groove and is located between the two damping blocks 11. The distance between the top and bottom outer walls of the card plate 12 is the same as the distance between the top and bottom inner walls of the mounting base 10. Cleaning cotton 13 is bonded to the side of the card plate 12 close to the path camera 2. The distance between the outer walls on the opposite sides of the two cleaning cottons 13 is the same as the distance between the opposite sides of the two path cameras 2. The cleaning cotton 13 and the path camera 2 are located in the same vertical plane, and the lowest height to which the cleaning cotton 13 can move downward is lower than the lowest height of the path camera 2.

[0024] In this embodiment, the path camera 2 is fixedly mounted on the left and right outer walls of the AVG vehicle body 1 .

[0027] The working principle of the above embodiment is:

[0028] When a certain amount of dust adheres to the path camera 2 on the outer wall of the AVG trolley body 1, the linear module 7 drives the fixing rod 8 and the connecting rod 9 to move downward, and the cleaning cotton 13 moves downward and contacts the outer wall of the path camera 2. The linear module 7 drives the cleaning cotton 13 to move up and down for many times, and the cleaning cotton 13 will clean the dust on the outer wall of the path camera 2. When the cleaning cotton 13 needs to be cleaned, the card plate 12 is pulled outward and taken out from the inside of the mounting seat 10. At this time, the cleaning cotton 13 can be cleaned for easy use next time.
